Costa Coffee warns over data breach

Costa Coffee has warned customers that it may have suffered a security breach.

In light of the news, the brand has reset passwords for all of its Coffee Club accounts and will introduce a “new format” for users’ passwords to help ensure improved data security for customers, according to the Register.

The Costa Coffee Club is the coffee company’s own loyalty scheme, offering five pence for every pound spent inside the store, along with unlimited Wi-Fi. In order to enter the club, customers had to provide a range of information, such as names, emails, birth dates and addresses.
